1.3 Power Requirements

(1) Input Voltage
•
+ 5 V
• It is unnecessary for this drive to supply +3.3 V and +12 V power supplies.
(2) Ripple
Maximum
Frequency
(3) Slope of an input voltage at rise
The following figure shows the restriction of the slope which is +5 V input voltage
at rise. The permissible range of +5 V slope is from 1V/20 μsec to 1V/20 msec,
under the voltage range is between 2.0V and 4.5V.
